Jill Zarin: Bethenny Isn't Pregnant

The Real Housewives of New York may be adding two new castmates for its third season -- but no baby for Bethenny Frankel, says her pal Jill Zarin.

Responding to yesterday's reports that Frankel, 38, is pregnant, Zarin insisted to usmagazine.com "It's a rumor!" at Monday's opening night party for the Broadway show Memphis. "I don't know why someone started that," she added.

But Zarin was still thrilled over news of Frankel's engagement to Jason Hoppy, her boyfriend of 11 months. "Isn't that great?! I called, reached out and sent something to the house," she said.

The Manhattanite had less to share about the two newbies (Sonja Morgan, 45 and an as-yet-unidentified woman) entering the Housewives fray this season. "I didn't know either of them before," she admits.
